I joined the University of Sheffield in 1993 and completed an undergraduate Physics Degree in 1997 and a PhD in Medical Physics in 2002. The focus of my PhD study was the interaction between balloon catheters and coronary stents during stent deployment and involved the use of both experimental and numerical techniques to address the problem.
Between 2001 and 2007 I worked on a number of projects addressing a range of biomechanical applications. These include; Bloodsim (EU FP7), a commercial project funded by the Trustees for the Bowling-Pfizer Heart Valve Settlement Funds, a study of deep vein thrombosis treatment funded by the EPSRC and a six month period spent in Tokyo, Japan funded by the RIKEN institute to develop models of blood clotting in cerebral aneurysms.
I currently teach a 3rd year undergraduate course in the application of numerical methods to clinical engineering problems. For current research projects please see the list below and associated web-links.
My research interest is the application of numerical techniques to the study of cardiovascular systems, with development of associated experimental validation methods. Application areas include coronary artery stenting, native and prosthetic valve function and venous haemodynamics. Such applications cover a range of technical areas including structural mechanics, Computational Fluid Dynamics, Fluid-Structure Interaction and multi-scale approaches for biological systems.
My teaching interests cover the application of numerical techniques to the study of biomedical problems, with emphasis on clinical applications. This includes a 3rd year course using Matlab and ANSYS to introduce finite difference and finite element techniques for the study of structural, fluid and thermal problems and the extension of this into 3rd and 4th year undergraduate research projects.
